' NUMERAL-WHEEL Lock.

To all whom it may concern:

lie it known that I, WARREN J. Inn, at citizen of the United States, residing at Kingston, Luzerne county, Pennsylvania, have invented new and useful Improvements in NumQral-VVhe-el Locl s,yof whicli'the following is a specification.

This invention relates to calculating machines of that type wherein the drive members and registering wheels or counters are shiftable relatively one to the other, and more particularly, to means to insure an effective connection between said drive members and counters and to prevent accidental Thus, in the well known \Vales type of adding machine, for instance, the counters are held disconnected from the drive n'iembers, when the machine is idle.

Upon an adding operation, after the drive members have been advanced, the counters drop to engage their pinions with the drive members. In a totaling and clearing, or a sub-totaling operation, the counters drop prior to the advance of the drive members. It has been customary, as illustrated in pat cnt to White, #940,766, dated November 23, 1909, to provide ineaiisto hold the pinions firmly in mesh with the drive members, to prevent any rebound of the counters which might resultin accidental disconnection from the drive members with a consequent liability of error in the registering operation. 1

The objects of this invention are to improve and simplify devices of this nature, to make them more compact, and reliable in operation, and to reduce the time required to assemble and adjust the parts thereof.

To these and other ends, the invention comprises certain novel features and comhination s. all of which will'be more fully dis closed hereinafter, and particularly pointed out in the claims.

In addition to the patent to \Vhite, noted, reference is also made to patent to Wales, #797,032, August '15, 1905, as showing a machine of the type to which this invention may be applied; and in connection with which, it will be illustra'ted and explained, though the invention s capable of use with other than the Wales machines.

invention applied thereto. Fig. 2 is a sectional view, the machine being idle. Fig. 3 is a side view, showing one of the locking inembeis ineffective position, parts being omitted. Fig. 4 is a detail perspective of one of the locking members. Fig. 5 is a detail perspective of one of the axle-supporting arms. Fig. 6 is a side view, similar to Fig. 3, but showing the other of said lookng members in operative position. Fig. 7 is a perspective detail of the locking members and cooperating-parts, removed from the machine.

Side frames 1 (Figs. 1 a d 2) support keyboard and registering mechanisms, the former comprising a series of spring-re stored keys 2, arranged in rows from 1 to 9, if the decimal'system is employed. Depression of a key in any row, rocks its respective lever 3 to project a stop 4 above a housing 5, said stops being arranged in rows corresponding to the rows of keys controlling t rem.

Counters 6 (Fig. 1) are individually rotatable on an axle. 7 extcndingacross the machine and mounted at its ends in arms 8 pivoted at f) to the respective side frames 1. Pinions 10 (Fig. 2) connected to therespective counters, mesh with racks 11 on drive members 12 whereby the counters are turned; 7

There is a drive member 12 for each counter, said members beingsupported' on forward and rear arms 13 and 14 swinging on a cross shaft 15 and a cross rod 16, respectively, extending across the machine. Drive springs 17 advance the drive memberstoward the stops. A restraining and restoring bail 18' mounted in arms 19 fixed to rock shaft- 20 journaled in theside frames 1, con- 13 to hold the drive members retractd. One end of an arm 21' fixed to the main drive shaft 22 enters a cam slot 23 in a crank-24 fast on the rock shaft 20 to lock the bail against accidental withdrawal.

A counter-shifting mechanism includes props 25, (Fig. 1) connectedto the axlesupporting arms 8 at 26, to normally hold the counters elevated in idle position with the pinions 10 out of mesh with their drive members 12.

A trip rod 27 1 and 2) suspended by arms28 from the cross shaft t'i and held in position by links 29 connected to arms 30 on the main drive shaft, supports the lower slotted ends of the props.

The-main drive shaft 22, when turned in an adding operation, swings arm 21, whose outer end traverses the cam slot 23 to turn the crank 24 and rock shaft 20 to withdraw the bail l8. Springs 17 thereupon advance their respective drive members 12, and swing arms 13, 14 forwardly, until arrested by the projected stops & against which the drive members strike, orby detainers 31 (Fig. 2)

overlying the stops. Protrusion of thestops hteanwhile theeonncr-ting links 29 have been swinging the trip-rod 27 in a descending arc to mesh the pinions 10 with drive members 12. Legs 32 F ig. 1) depending fromarms 8 normally have their feet in line with seats 33 on the side frames and as the trip rod descends, said feet rest on the seats to delay the engagement of the pini'ons and drive members until the latter have reached their advanced positions. Duringtheinitial stroke of the main drive shaft22, 'the ends of the tri rod 27 traverse the slots in the lower en s of the props and the slots in bridle links 34 connected to the legs'32, at35. Toward the end of said initial stroke, the trip rod strikes the ends'of the slots in the bridle whereupon the axle 7 with its supported parts, drops and ineshes the pinions 10 with the racks 1.1, to'connectthe counters and drive members.

The main drive' shaft, on its return stroke, presses the bail 13 against the advanced arms 13 of the drive members to restore the latter; and the drive members, as they retire, turn the counters to register or accumulate an amount corresponding to the values of the keys depressed. The trip rod 27 on such return stroke, at first shifts idly backward, but after the drive members are retired, it quickly swingsin an ascending arc to raise the props 25 and disconnect the counters and drive members. Restoring springs 36 (Fig. 1) return the delaying legs 32 to normal position. I A

Depression of a special clearing key 37 (Fig. 6) rocks set levers 38 fast on crossshaft 15 and shifts links 39 connecting said levers with the delaying legs 32 to displace the latter relatively to their seats 33. A connection 40 (Fig. 1) between an arm 41 of one of said levers 38 and a connecting bar 42 guided on studs 43, enables the key 37 to shift said coniiecting bar. A cam face 44 on the bar wipes a crank 45 on a shaft 46, to

drive members 12 prior to the withdrawal of the restraining and restoring bail 18, so that the drive members turn the counters on their advance, instead of on their retirement, to reverse the direction of rotation of the counters until the latter are reset to their zero positions in a manner well-known in the art and explained, for instance, in patent to Mc- Farland, 842,232, above referred to.

Thrust bars 49, (Fig. 1) pivoted at 50, to counter-restoring levers 51, preferably journaled on the cross-rod 16, normally rest on pins 53 carried by the props 25, and overlie studs 52. These studs rock out from under the bars when the clearing key 37 is set, and on the initial stroke of the main shaft 22, the bars 49 follow the props as they descend until arrested by the studs 52 (Fig. 6). A

The locking device 48 partially releases the clearing key 37 at the end of the initial stroke and at the beginning of the return stroke, springs 54 restore the set levers 38 to normal position. The set levers during their restoration, press the studs 52 against shoulders 55 (Fig. 1) on the thrust bars 49 in the well known manner to force the bars backwardly and rock restoring levers 51, which contact the legs 32 or-projections 56 (Fig. 6) thereon, tojdisconnect the counters from their drive members while the counters remain at zero, and before the retirement of the drive members. The main shaft. then causes the restoring bail 18 to retire the drive members and also returns the trip rod 27 and props 25 to-normal positions to support the counters in idle position. During the return of the props, the pins 53 thereon, release. the thrust bars 49 from the studs 52 to enable the re storing levers 51 to return to normal position out of the paths of the projections 56 on the legs 32, as shown in Fig. 11

By holding the special key 37 depressed, on the return as well as the initial stroke, the counter'restoring mechanism 49, 51, 32 is prevented from operating, so that the counters and their drive members remain connected, to the end that the amount. displayed by the 'counters prior to the depression of the key 37 and rolled 01f on the initial stroke after the key is depressed, is rolled .back on the return stroke, and the eountets will display the same amount at the end of the operation, as was registered at the commencement thereof. This operation is used in taking subtotals with a printing mecharate,

nism (not shown). Under these conditions, the thrust bars 49 are tripped by pins 53 prior to the restoration of the set levers 38 so that no operation of the counter-restoring levers 51 takes place.

The foregoing-construction is old and only constitutes part of the present invention in so far as it is Combined with the new parts now to beset forth.

In operating the machine, the pinions 10 drop suddenly and with some force into mesh with their racks 11, and to hold them in mesh therewith and prevent which might render the operation inaccu- I have contriyed a simplified and more compact means for locking the counters in effective position. A catch or locking member 57 (Fig. 1) pivoted at 58 to the side frame 1, carries a head 59 confronting a keeper 60 arm 8, to fit over said keeper when the pinions drop into mesh with their drlive members. A sprin 61 (Fig. 3) presses the tail 62 of said catch or a lip or follower (33, thereon, against the rear edge Qfthe'adjacent prop 25. The tail, under the'influenee of its drive spring, latter is swung forwardly by the trip rod 29 on the initial stroke of the main shaft, in' an adding 0 eration, to shift the head 59 toward the lieeper Gdagainst which it finally rests, as the prep continues its ad- Vance, so that at the moment the counters reached their ;be released as soon as any danger drop, with the keeper, toward the end of the initial stroke, the spring snaps the catch over the keeperto hold the counters against a rebound (Fig. 3). The catch and keeper are so positioned relatively to each, other that the keeperdoes not clear the head of the catch to enable the latter tov become ef fective, until the counters have about lower limit of travel.

. The catch remains effective during the retirement of the drive members on the return stroke (atwhich time the registration of the amount set up on the keys takes place) until the prop on its return, contacts the lip 63 and swings the catch to inactive position against the tension of itsdrivc spring 61. Obviously, the prop must release the catch from the arm 8. or the keeper 60 thereon, prior to the ascent of the trip r od which restores the counters to idle position, but as such asoentoccurs at the end of the return stroke, there is time withinv which to shift -the catch the slight distance newssary to release the keeper, after the effective retirement of the drive members and prior to the restoration of the counters, and in any event, the catch may of a rebound is past.

It will be remembered that'in. taking a. total or clearing "the machine, the counters drop to effective position withi l air drive preferably pivoted 4 keeper (30.

a rebound'to a. totaling 'o-r clearing operation,

mounted on the axle-supporting follows the prop as the '27 to lift the counters -will be retired by said shoulder.

Should a subtotal be taken,

members at the beginning of the initial stroke, and to hold them effective at that time, I provide a second catch or locking member 64 (Fig. 1) similar to catch 57 and coincidently therewith, the head (35 of the catch (34 confronting the The tail (56 of this total or clearing catch, or a stop (37- (Fig. 7) thereon, normally contacts arm 41 of the set lever 38 whichholds said catch at rest in the adding or idle operations of the machine. Depression of the controlling key 3.7 preliminary withdraws said arm -11 of the setting. lever and frees the catch to the action of its drive spring (38, which presses the catch 64:, or a lug or follower (39 thereon, 25. ()Irthe beginning of the initial stroke, the thrust bar 42 drops until caught 'on stud 52 and interposes a shoulder or stop .70 thereon in the path of the retracted catch 57 or of the lug .63 thereof, to maintain catch 57 substantially idle, throughout the clearing operation.

On the initial stroke, in a totaling and clearing operation, the lug 69 follows the prop 25 to enable the spring 68 to snap the head (35 over the keeper when the counters have reached. their limit .of travel. Upon the restoration of the key 37 at the end of against the prop the initial and the beginning of the returnstrokes, the set lever 38, in retiring to its normal position, forces its arm 41' against the stop 67 to retract the catch or locking member 64, and thereby enable the trip rod to idle position prior to the restoration of the drive members. The arm 41 in returning, presses the thrust bar 49 rearwardly, in restoring the coun ters. The thrust bar, under such pressure,

retracts the item locking member'57 due to the contact of the shoulder or stop 70 with the lug o-r follower 63. Hence it is immateriaLwhether the item locking member functions or not during a total or clearing-operation, as should it become effective, it

Preferably, however, the item locking member 57 is held ineffective during a totaling and clearing operation. locking member (34 must be retracted prior to the operation of the restoring lever 51, to permit which, the parts are so arranged that upon the start of the return stroke, the arm 41 immediately shifts the locking member ti t, and because of a slight playbo- -tween the stud '52 on the arm and the sh0ul I der 55, (as exaggerated in Fig. 6 in dotted lines), the catch is retracted prior to the eflective operation of-the'restormg lever 51. the operation Obviously the total of the total locking member (54 is thesame,

except that it its return, which contacts the lug or lower (59. It has is retracted by the prop 25 on 01; been explained that, in a &

sub-total operation, the set lever 38 is not restored until the end of the return stroke, and hence cannot retire the total catch 64 in subtotaling operations.

The loekin mechanism above set forth may be duplicated on theoppositegside of the-machine from that illustrated.

Changes may be made in' the form and arrangement of the several parts disclosed without departing from the spirit and scope of the invention.
